Actual loyalty tends to get nugatory rewards: a week's extra holiday for 25 years of service?

真正的忠诚往往会得到没什么价值的奖励：25就能增加一周的假期？

Assuming flexible money-wages, the quantity of money as such is, indeed, nugatory in the long period; but the terms on which the monetary authority will change the quantity of money enters as a real determinant into the economic scheme.

假设货币灵活的，货币数量本身在长期内确实零的；但货币当局改变货币数量的条件作为真正的决定因素进入了经济计划。
